FAN CONTROLLER CHECK
1. Remove condenser fan motor connector.
2. Start the engine and run it at idle.
3. Turn the A/C switch to ON and maintain the coolant temperature at 80 °C (176 °F) or less.





4. When measuring the voltage between the fan control module-side connector terminals, check that the value changes repeatedly as indicated by (1) - (3) below.
(1) 0 Volts
(2) 8.2 ± 2.6 Volts
(3) Battery positive voltage ± 2.6 Volts
5 If the voltage does not repeatedly change as indicated, replace the radiator fan motor and the fan control module assembly.
